Hyperice X Knee - Portable Contrast Therapy Device Seamlessly Switches Between Hot and Cold Therapy in Seconds

I bought this to recover from a total knee replacement. I’ve had multiple scopes, rotator-cuff surgeries, and other ortho procedures, and I’m done dragging around a cryo cuff with ice and water—too loud, messy, and awkward post-op. Enter the Hyperice X Knee. I wanted an occasional alternative to the ice machine, but it’s better than expected. It’s easy to turn on, cools quickly, and holds a precise, consistent temperature—never froze my incision—and I could keep it on longer without discomfort. Battery life beat my expectations, and the extra-long power cord made it easy to move around the house. The iOS app is handy and kind of cool: you can set temperature and run a Cold Therapy routine up to 20 minutes. You can’t run it indefinitely—understandable for safety reasons—but at night I can skip the app and press a couple of buttons on the device to start a 15-minute cold session. Super convenient for middle-of-the-night relief. Since getting it, I haven’t used my old ice machine once. Bottom line: for post-surgery recovery, this has been a surprisingly perfect solution even though that’s not its primary marketing angle. I’m using it as I write this and couldn’t recommend it more. Pros Easy to turn on; app optional Consistent, controlled cooling (no over-icing) Quiet and portable; no ice or water to juggle Better-than-expected battery life Long power cable = easy to move around App routines up to 20 minutes Cons Can’t run indefinitely (safety limit) Pricey—but it replaced my ice machine entirely TL;DR If you’re recovering from knee surgery and hate dealing with an ice bucket system, this is worth it. Precise, quiet, portable, and genuinely helpful.

This is a great device that does what it advertises. The cold is quite cold and the warm is very warm, if not hot. It is great to have for routine treatment of inflammation or relief after workouts. If you have bad knees (ACL, meniscus tear, arthritis, etc) the ability to sit down and immediately have cold or warm therapy is fantastic. While there is certainly a place for ice and compression devices (I have several) this does the trick for short sessions without the hassle of ice cubes. Is a device that you need? No. But, it is a device that is convenient and works in seconds? Yes! The battery is long enough for several sessions and it is easy to plug in to use if you are out of battery life. There are two downsides: 1) there are 3 sensors in the front that cool or warm your knee so your entire knee (front and back will not be treated) 2) if you have short, thicker legs, the device will be tight. Extension straps are included. Some people have commented that their Hyperice X stopped working after a while. For this reason, I purchased the Amazon extended warranty. A small price for peace of mind. If for some reason I lost this device, I would definitely purchase another one. In fact, I’m thinking about getting a second for my other knee. 😀

....and that's - get hot and cold. Contrast hydrotherapy is a simple yet effective way to speed up healing and improve circulation to the affected area. The problem is, it's a nuisance to apply a heating pad, then a cold pack, then a heating pad, etc. This unit does it for you, thus making it much more likely that you'll actually do it. It gets cold but I wish it got a bit colder. It gets very hot, hotter than I need (but it's adjustable, so not a problem) The quality is very good, it's easy to use, and the app is simple. I'm very happy with it. I use mine everyday and it's great.

This is a rechargeable heat and ice therapy device that wraps around the knee with 3 adjustable Velcro straps. It works by a rechargeable battery as well as being plugged in. It is easier to use the Bluetooth Controls through the app, than it does manually. The battery is at the top of the device. It does get warm during use, but imperceptible on the knee. There are 5 fans that work on cooling a pad on the backside of the unit. It definitely gets ice cold to me. The heat is also quite warm to hot. On the hot setting, it does get quite hot to the point of being uncomfortable but it works extremely well. The beauty is that I can adjust the temperature to my level of comfort. You have the option for heat, cold or combination treatment. I personally like the cold function over heat. During the cold therapy the sound is a very low, like a desktop fan on the lowest setting. The straps adjust easily and there are additional straps for larger sized individuals. I find the item is high effective. It can work on other body parts but won’t stay on the area like it was designed for the knee but it should work on the ankle or foot, just fine. Price is high but there is nothing made quite like this. I find this to be very versatile. Its weight is good enough for travel. It is more versatile than my Ice machine. Definitely recommend it. Update: Nov 2023 I have taken it on a trip to Iceland. It is so nice to have something portable that can do the modalities it does. Now I don’t have to worry about being away from things I used to ease my symptoms, no matter where I travel. Not only can I use this for my knee, but I have used it on my lower back, ankle, and foot, too. I love the versatility, plus the duration of treatment is spot on!

I upgraded from the compression boots to this. I had ran a marathon 2 weeks ago and was experiencing some rad pain in my left knee. I was pushing through my runs when my pain came across when running. I got this device and let me say it has erased my pain within less then 5 hours of having it. The two biggest things I love are the temperature contrast therapy, and the battery life. Shorten your sessions to 15 mins and don’t do the highest or lowest temperature and you will get the most use out of the two. It’s a great device I absolutely recommend for high intensity athletes this is a GAME CHANGER. and so are the compression boots they have! also not so sure about the other knee knee brace they have that’s higher in price but this has been sufficient for me!
